Extending between the frames of the ina-- chine under all of that part thereof covered tween the centers of theroll w and the feed.-

by the roll 0 and the feed-rolls (to be de scribed) is a table r of Wood or other mate Arial on which the belt t is supported during the cleaning operation. -Next forward of the scraper-roll o is Ia small feedrolls on a shaft t, also supported in yielding bearings like the scraperroll. The fiaps z which hold 'the plaques will pass under the feedrolls .s thus binding the plaques f/ to the belt at about the time the scraper-roll first begins to bear on the plaque, and the latter is thus held firmly against slipping by being held firmly against the belt across the entire front end thereof, and the pressure of this feedroll s is sutiicient, after theflap la, has passed under it. to hold the plaque from slipping backward under the action of the scraper.-

roll. Next beyond the feed-roll s is a wiper-` roll 'u mounted on a shaft lw, and covered with an enveloping strip of cloth m to maintain which on the roll without wrinkling it is preferably spirally Wound thereon, asv shown in Fig. This roll is also mounted in yielding bearings, as is the small feed-roll y/ next forward thereof. andthe distance be# roll y, is such that the flapl h will pass 'luide-r the roll 1/ in time to grip the forward endLA of the plaque before the rear end of the flap /L passes out from under the rollo, this being necessary because the latter lroll runs con trary to the direction of movement of the plaque,.and unless they forward'endofthe latter were so gripped the wiper-roll would pull the loose end out from under the flap h. Atsome point below the roll d a suitable table may be placed -to receive the 'cleaned plaques which will beautomatically released I from the flaps as the belt passes over the roll d and falls on thetable.

During the operation 'of .the machine-,.theiintf7 0 of the plaques will be thrown .centrifugally chocolate which 4is freedv fromthe surface away from the roll o in order to prevent these particles from falling back onto the plaque or apron, receptacles are provided The driving-shaft of the machine is indicated by 4, and from it, by means of the' gear 5, movement is imparted to the roll o by the gear 6, and tothe Wiper-roll v by the gear 7. On the end of the shaft p of the scraper-roll is a pinion 8 meshing with the gear 9 -on the end of the' shaft l -whereby movement is imparted to the feed-rolls.

-Similarly on the end of the roll e is a pinion 10 meshing'withthe gear 12 on the shaft'of i the feed-roll y, on the end of which, in turn, is a pinion 13 meshing with the large gear 14 on the shaft Vb whereby movement is imparted to the endless belt e.

. As heretofore stated, certain of the rolls are mounted in- 'spring bearings whereby they may yield vertically when the flaps h pass thereunder, and to permit such yielding movement of the rolls, the connection'between the ends of the latter and the short shafts on which the various driving gears are 'mounted are. made in the form of universal couplings 15 of any Well known type. While the type of scraping device heretoforedescribed is they preferred one, any

be applied to the'surface of the plaques is deemed to fall vention. y A One construction for example, which might be .#substituted therefor to roduce this effect, is illustrated in'Figf'et, an it consists in'mountingon an endwise reciprocat-A within the scope of the ning shaft or bar 16, the U-shaped spring-tingers 17 which are of the same type as those `used on the roller lheretofore described, though longer, andare 'adapted .to bear yieldingly e..

l against the surface. of theplaq ue, means ing provided to impart reciprocating end- Wise .movement to the shaft 16, whereb as .the plaqueg, moving in the direction o the arrow, asses under said fingers, all parts ofj the sur ace 'of theV plaque would -be covered by the scraping movement of the fingers4 and v subjected to theL lyielding ,scrapingaction necessary to remove the adherent particles of coating material.

lVhat I claim, is: v

1. A machine of the class described comprising an endless belt, exible and pliable means stitched at one edge to `said belt to removably secure a paper plaque or the like at the forward end thereof in a temporary position on the belt, whereby said plaque will .move with the. latter, and a device mounted in operative relation to 'the'surface of the belt to apply a scraping action to Y the plaque.

2. A machine of theclass described compris- Ling an endless belt'having las extending transversely thereof secured to t e belt by one edge to receive the end ofa paper plaqueor the likeinserted between the Hap and the surface of the beltf-\whereby when the iiap runs under a feed-rohthe plaquel Will be held in fixed position on thebelt, together With means to subject `tlm-plaque orr the like. to thev action of a devicel for cleaning thesurface thereof.

- 3. A machine of the' classdescribed comprising a roll having spring-'fingers 'secured to the surface thereof substantially tangential thereto, adapted to ap ly a spring-like past the roll, and feed-rolls bearing on the -belt to hold the strip against movement onv lthe belt.

' 4. A machinev of the class described comprising a vroll having s ring-fingers secured Itangenti'ally to tlgesurtace thereof, adapted to apply a spring-like scraping action to the surface of a strip of 'material moving past the roll in contact with the ends of the fingers; an endless belt to carry said strip ast the roll, and feed-rolls bearinggon the be t toA
